How can you tell if your cat has lyme disease?

If the surrounding area is swollen or red, the dog may have an infection from the tick bite, but if the skin looks and feels normal around where the tick was removed, there shouldn't be any connection to the tick bite. Also, make sure you removed all of the tick's head and mandibles from the bite spot, as this could keep the wound open allowing infections to enter.

Always see a vet for a final answer.
